Abstract

Atrial fibrillation (AF) is one of the most common types of heart arrhythmias and it leads to increased risk of stroke and heart attack. We proposed improved method for automated AF detection with additional aggregation of short AF episodes to provide more reliable information on risk for the patient. The aggregation parameters underwent optimization process and evaluation study has been carried out with a use of two databases provided by PhysioNet.org. Final results showed that the new method for automated detection of AF episodes was capable to detect more than 96% of all reference AF provided by the MIT-BIH Atrial Fibrillation Database, and above 93% for the Long-Term AF Database. At the same time less than 7% of the detected AF were false episodes for both databases. The proposed method can be easily implemented in the mobile instrumentation for long-term monitoring where the computational power is usually limited.
